are you following abarth's suggestion re: CORSMode?

the word "attribute" is more of a WebCore/html-ism and shouldn't be present down
here in the depths of media engine code!

+
   // |url| - URL for the resource to be loaded.
+  // |cross_origin_attribute| - HTML media element's crossorigin attribute.
   // |first_byte_position| - First byte to start loading from,
   // |kPositionNotSpecified| for not specified.
   // |last_byte_position| - Last byte to be loaded,
   // |kPositionNotSpecified| for not specified.
   // |strategy| is the initial loading strategy to use.
   // |bitrate| is the bitrate of the media, 0 if unknown.
   // |playback_rate| is the current playback rate of the media.
